ACKNOWLEDGEMENTS First and foremost I would like to thank Professor Constantine Polymeropoulos for his professional and personal guidance and many, many useful and enlightening discussions on the topics of aviation fuel properties, heat and mass transfer, modeling fuel vaporization, and experimental methods and procedures. His leadership and direction has been most valuable during my time spent here at the university. I would also like to thank Mr. Richard G. Hill and Mr. Gus Sarkos at the Fire Safety Branch of the Federal Aviation Administration’s William J. Hughes Technical Center for the opportunity to perform this research at the technical center and for the many conversations with them about fuel tank safety. Their knowledge, wisdom, and insight on the subject of fuel tank safety is truly unmatched, and was extremely valuable in writing this thesis. I would like to thank Mr. Steven Summer and Mr. Joseph DeFalco for their help in the development of the experimental apparatus, assistance in obtaining materials required to complete the research, and many useful discussions about fuel tank safety. Much thanks and appreciation also goes to the entire staff of the Fire Safety Branch of the Federal Aviation Administration’s William J. Hughes Technical Center for aiding in completing this research. I would also like to thank the Department of Mechanical and Aerospace Engineering for the ability to study under the tutelage of the many professors with diverse academic backgrounds and great knowledge of the engineering sciences. vi
DEDICATION This thesis is dedicated to my parents, Richard C. Ochs and Florence J. Ochs. Their endless love and tireless efforts have been of great help during these times and truly reflect in my achievements in academia and accomplishments in life. vii
